George saves 18% of his total gross weekly earnings from his 2 part-time jobs. He earns $6.25 per hour from one part-time job and $7.50 per hour from the other part-time job. George works a total of 40 hours between the two jobs each week. What additional information is needed to determine the amount of his earnings he saves each week?

how much of the 40 hours he works at each job

To determine the amount of George's earnings he saves each week, we need one additional piece of information: the number of hours he works for each part-time job.

Let's say George works x hours for the first part-time job and y hours for the second part-time job. We already know that he works a total of 40 hours between the two jobs, so we can write the equation:

x + y = 40

Now, we also know that George earns $6.25 per hour from his first part-time job and $7.50 per hour from his second part-time job. So, we can calculate his weekly earnings from each job:

Earnings from the first job = $6.25 * x
Earnings from the second job = $7.50 * y

To determine the total amount George saves, we need to find 18% of his total gross weekly earnings. However, since we don't have the specific values for x and y, we cannot determine the exact amounts George earns from each job and therefore cannot calculate his savings at this point.

Therefore, the additional information needed to determine the amount of George's earnings he saves each week is the specific number of hours he works for each part-time job, or the values of x and y.

To determine the amount of George's earnings he saves each week, we need to know the total number of hours he works in each part-time job. Currently, we have the hourly rates for each job ($6.25 and $7.50) and the total number of hours worked (40 hours), but we don't have the breakdown of the hours between the two jobs.
